Them’s fightin’ words, we know, but top to bottom, there isn’t loser on this year’s list. With Next Big Thing moving from Sunday to Saturday at the 1-800-Ask-Gary Amphitheatre in Tampa, it’s primed to be one of the most fun in recent memory. Here’s a breakdown of the lineup, complete with a schedule of performance times.

MAIN STAGE

Sublime With Rome (9:45 p.m.): Thirteen years after the death of singer Bradley Nowell, Sublime’s surviving members recruited sound-alike Rome Ramirez to fill in behind the mic. A few lawsuits and one name change later, classic reggae-rock jams like What I Got and Wrong Way live on alongside new tracks like Panic.

A Day To Remember (8:40 p.m.): With a raging blend of razorblade riffs, hummable hooks and a jaw-dropping stage show, the Ocala metalcore quintet is one of the biggest young punk and metal bands in the country. They headlined this summer’s Warped Tour.

Bush (7:20 p.m.): After an eight-year hiatus, grunge heartthrob Gavin Rossdale and Bush returned in 2010. They’ve been touring ever since, proving the public’s appetite for Comedown and Everything Zen knows no bounds.

Foster The People (6:20 p.m.): Could you go anywhere this year without hearing Pumped Up Kicks? Us neither.

Cage The Elephant (5:20 p.m.): Another dynamic live band, this Kentucky group rose to fame with the radio hit Ain’t No Rest For the Wicked, but showed potent musical growth on sophomore album Thank You, Happy Birthday.

Taking Back Sunday (4:20 p.m.): Combining the vulnerability of Springsteen with the punk riffs of the Misfits, Long Islanders Taking Back Sunday are proof that emo didn’t die in 2003; it just got louder.

Young the Giant (3:20 p.m.): These SoCal indie kids hit big in 2011 with songs like My Body and Cough Syrup. How big? Big enough to perform on the MTV Video Music Awards and land their own episode of MTV Unplugged.

SIDE STAGES

AWOLNATION (2:25 p.m.): The weirdest hit rock song of 2011 might be Sail, the trippy blues/pop/metal/dubstep single by AWOLNATION frontman Aaron Bruno. But it totally works.

Grouplove (12:20 p.m.): A bright, beachy young collective with impressive harmonies and sparkling singles (Colours, Naked Kids), Grouplove credit 97X with being one of the first big radio stations in the country to play their music.

fun. (11:30 a.m.): This indie pop group used to sound so precious it hurt — until they released new single We Are Young, an Arcade Fire-like call to arms that hints at the grand pop ambitions of their forthcoming second album, Some Nights, due in February.

Sleeper Agent (10:40 a.m.): How are there two bands from Bowling Green, Ky., on this bill? Like their pals Cage the Elephant, Sleeper Agent are shaggy garage rockers with a catchy sound (see their single Get It Daddy).

Khora (10 a.m.): This year’s local band contest winners, Seminole’s Khora infuse their good-time reggae-rock jams with a little blues, a little funk, and just a hint of psychedelia.
